Electron Holography - Electromagnetic Fields

Electromagnetic Fields

It is important to shield the interferometric system from electromagnetic fields, as they can induce unwanted phase-shifts due to the Aharonov-Bohm effect. Static fields will result in a fixed shift of the interference pattern. It is clear every component and sample must be properly grounded and shielded from outside noise.

Famous quotes containing the word fields:

    “For wheresoe’er I turn my ravished eyes,
    Gay gilded scenes and shining prospects rise,
    Poetic fields encompass me around,
    And still I seem to tread on classic ground.”
    —Joseph Addison (1672–1719)
